Remapping buttons not working and says "ENTER or ENTER J1 JoystickButton J2 JoystickButton J3 JoystickButton J4 JoystickButton"

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Pressing the two buttons to get to the input controls menu
2. Pressing 'B' for remapping
3. Pressing the desired button

What is the expected output? What do you see instead?
Expected to see the button I pressed remapped to that particular input (ie 
player button 1) but instead I get the message "ENTER or ENTER J1 
JoystickButton J2 JoystickButton J3 JoystickButton J4 JoystickButton"

What version of the product are you using? On what operating system?
1.7 on iOS 4.3.3 iPad 2

Please provide any additional information below.
I tried to delete the cfg file in the roms/imame4all as suggested but there was 
no cfg file at first and when I did save the settings and deleted the cfg file, 
the same problem occurred. Please help me fix this. Thank you for your time an 
effort with this wonderful program!
